All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.

What is the peak-to-peak voltage in a circuit with an rms voltage of 120VAC?

ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41


What is difference between amplitude and peak value?

It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".

A: Take 115 volts and multiply by 2.82. The frequency does not matter but he voltage does


What is the rms value for 300mv peak to peak?

To find the root mean square (rms) value for a voltage given in peak-to-peak (Vpp), you need to divide the Vpp value by 2√2. In this case, the Vpp is 300mV, which is equivalent to 0.3V. Dividing 0.3V by 2√2 ≈ 2.828, the rms value is approximately 0.106 V.


What is the value and peak to peak value of 12v what are the voltage values of rms peak to peak and half cycle average?

For a 12V peak voltage (V_peak), the peak-to-peak value (V_pp) is 24V, as it is twice the peak voltage (V_pp = 2 * V_peak). The root mean square (RMS) value is approximately 8.49V, calculated as V_rms = V_peak / √2. The half-cycle average voltage is about 7.64V, calculated as V_avg = (V_peak / π).


How you can prove the Peak voltage?

Use an oscilloscope. That shows the voltage waveform and you can read the peak value.


How does the peak value of an alternating voltage compare to its quoted value?

The quoted value is usually RMS value, i.e it is lesser than the peak value of the voltage, therefore the peak value is sqrt(2) times the quoted value. (it is a sine wave)


What is the peak value of a household appliance that uses a 230 VAC source?

Peak value is 1.414 times the RMS voltage. On a 240 volt circuit the peak voltage is 240 x 1.414 = 339.36 volts. The peak to peak value is twice this.


Volts peak is equals to dc volts?

"Voltage peak" is generally used to denote the maximum(amplitude) of AC voltage supply. It can not be approximated as dc value. The closest approximation one can make for dc value of a ac supply is the RMS(root mean square) value of the voltage. So that the ohmic loss caused by the given AC voltage supply is equivalent to that caused by a dc supply having value equal to the RMS of this AC supply (for given impedance & time).


What is peak to peak voltage?

Conversions of RMS voltage, peak voltage and peak-to-peak voltage. That are the used voltages. The expression "average" voltage is used for RMS voltage.Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".Answer'Average' is not the same as 'root mean square'. As the average value of a sinusoidal voltage is zero, you cannot convert it to a peak-to-peak value.


A technician uses an oscilloscope to measure the peak value of an ac wave he tells you that the voltage has a peak value of 100v what is the rms value of the voltage?

100v divided by 1.41


Why is the peak amplitude of voltage load lower than the amplitude of voltage transformer?

Unless otherwise stated, the value of an a.c. current or voltage is expressed in r.m.s. (root mean square) values which, for a sinusoidal waveform, is 0.707 times their peak value. The output of a voltage (or potential) transformer is no different, its measured voltage will be its r.m.s value which is lower than its peak value.
